Prior to the establishment of a state agency to coordinate and assist in Royally initiated projects, much of the administrative support for His Majesty's projects came from a section in the Office of His Majesty's Principal Private Secretary. When the projects became more complex, he called on the government to set up a specific organisation to handle them. Accordingly, in 1975, His Majesty's Personal Affairs Division was established in the central government to manage the myriad aspects of project design and implementation.
In 1981, he created the Royal Development Projects Board whose members comprise leaders in Thai business and society. The board, in effect, takes over a project once the experimentation phase has been declared successful. It thus serves as the coordinating agency which employs state technical and human resources.
